More inside track from a Portugeezer:
AVB has several problems. First of all, his tactics are NOT that good. In the portuguese league there were many games that were walking to a draw or loss by Porto and out of nowhere they would get a penalty or the other team would get a red card or a freekick or something. That's not to say he is a bad manager, like the worse in the world.
No, he's not that bad. He's just average. At Académica he didn't do anything special and he benefited alot of the work of his predecessor, Jesualdo Ferreira, the team that he had set up and the players he had chosen.
Also, let's not forget, that team had Radamel Falcao, one of the best strikers in the world.
So, if he has all these problems how did he trounce the Portuguese League? Well, he got lucky. Lucky in the sense that Sporting was completely broken from the inside, Benfica thought they would win every single game simply by being there and Braga simply decided to not give a arse.
He's a mediocre manager, he has nowhere near the competence to join a truly superpower of football, at least not yet. I still think he can surprise me, but to be frank, after his display at CFC I can only assume I was right, at least for now.
You see and then I read something like that, which confirms what you don't want to suspect, and I lean towards Rafa again.
